Let's start jamming Ráfaga - Una Cerveza chords, practice the chord sequence D, Gm, Eb, Bb, D, Bb, F, Bb, D and Eb. I suggest starting at a calm pace of 49 BPM, and as you gain confidence, approach the song's BPM of 99. With Bb Major as the song's key, tweak the capo to cater to your vocal pitch and chord likes.
